Claim
On June 5, 2018, Chang announced his retirement from TSMC
Correction

The retirement was announced in October 2017, not on June 5, 2018. June 2018 was the planned effective retirement date after TSMC’s annual shareholders’ meeting.

Full reasoning

TSMC’s own filings show that Morris Chang announced his retirement months earlier, in October 2017.

A TSMC Form 6-K filed with the SEC on October 19, 2017 includes a recap item reading: "Dr. Morris Chang Announces Retirement in June 2018 ... (2017/10/02)." A later TSMC Form 20-F for fiscal year 2017 likewise says that in October 2017 Chang announced his plan to retire from the company in June 2018.

So June 5, 2018 was the retirement/effective transition period, not the date of the announcement.

Claim
They married in 1952, when they were both 22 years old.
Correction

These dates do not add up. Morris Chang was born in 1931, and a later account based on his autobiography says he married his first wife at age 22, which would place the marriage in 1953 or 1954, not 1952.

Full reasoning

The statement is chronologically inconsistent with documented information about Morris Chang's age.

MIT News states that Chang "was born in China in 1931." A 2024 World Journal report summarizing the second volume of Chang's autobiography says that he and his first wife were the same age, that Chang was 20 when they fell in love at MIT/Boston University, and that they married at 22.

If Chang was born in 1931, then a marriage at age 22 would fall in 1953 or 1954, not 1952. So the sentence "They married in 1952, when they were both 22 years old" cannot be correct as written: either the year or the stated age is wrong.
